PATENT OFFECE..

PENNSYLVANIA, ASSIGNOR TO SANNER LUBRICATOR.

Application filed May 11, 1922.

T0 all whom t may concern.'

Be it known that I, CELnsTlN SANNER, a citizen of the United States of America, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Lubricators, of which the following is a i specilication.

This invention relates to lubricators and it has more particular reference to oil cups such as are usually employed upon machines and the like which are subject to varying degrees of vibration, the primary object thereof being to provide a lubricator or oil cup the feed wherefrom is in the nature of a splash dependent functionally upon and automatically varying in direct relation to the degree of vibration of the part on which said lubricator or oil cup ismounted. In other words, this invention aims to provide a lubricator or oil cup which when mounted on a piece of machinery or the like that is subject to varying or a constant degree of vibration, the part or parts lubricated thereby will be automatically supplied with lubricant in direct proportion to its need; that is to say when the part lubricated is slightly vibrated the feed of lubricant will be compa-rativelyslow or according to accepted requirement to keep said part prop erly lubricated; and on the other hand when said part is subject to a higher degree of vibration the supply of lubricant will automatically increase in direct proportion consonant with proper lubrication or the i11- creased Fahrenheit temperature of said part resulting from a higher velocity of the rotating or reciprocating member being lubricated.

Another object of this invention is to provide a vibratory splash-feed lubricator which is devoid of any valve elements while at the same time it is of a character that is automatic and positive in its action when applied to the vibrating parts of machines or engines.

A further object of'this invention is to provide a lubricator or oil cup characterized by the fact that the lubricant creates its own seal or cut-ofi", when the movable or vibrating part on which said lubricator or oil cup is mounted comes to a condition or state of restu Serial No. 560,171.

A still further object attained by this 1nvention is the provision of a splash-feed vibratory lubricator which includes a minimum number of parts7 the same being of a character and design that ensures ease in their manufacture and assembly, with a resultant saving in time and labor in production.

With the foregoing and other objects in view as will be more apparent from the following description my invention consists essentially of an oil cup or lubricator provided with a sealing pan having apertures therethrough for the discharge of lubricant when said oil cup or lubricator is subjected to vibration, in combination with a superosed dished diaphragm having an outlet 1n direct transverse alignment with the aforesaid apertures in the sealing pan whereby an automatic cut-off of the lubricant inheres when the device is at rest.

In the further disclosures of the invention reference is to be had to the accompanying sheet of drawings illustrative of one practical embodiment of my invention, and in which like characters of reference designate the same or corresponding parts in all the views.

Figure 1 is an elevational view of an Oil cup embodying my invention.

Figure 2 is a central vertical section through the oil cup shown by the preceding Figure.

Figure 3 is a top plan view of the dished diaphragm hereinafter more fully described; and,

Figure 4 is a plan view of the sealing pan likewise later on more particularly referred to.

Referring more specifically to the drawings, the numeral 5 designates the main body portion or reservoir ofmy novel lubricat'or or oil cup the same being cylindrical and having an integrally formed lower extension 6 of concavo-convex formation appropriately'fashioned with a polygonal and axial part 7 terminating in a screw-threaded nipple 8 by means of which the device can be readily secured in place or removed as desired. It is to be here particularly noted that the aforesaid concavo-convex part or lower extension 6 is of less diameter than that of the main body portion or reservoir 5 thus providingY an internal shoulder or seat 9 for a purpose later on explained. Furthermore the extreme lower end of the screw7 threaded nipple' 8 is closed in at 10 and axially holed at 11 to provide a discharge orifice for the lubricant.

Fitting easily within the main body portion reservoir 5 and seating on the aforesaid shoulder 9 is what .l term a sealing pan l2 which is preferably of the (lished formation shown. This sealing pan 12 is appropriately made of thin sheet material., fashioned to provide a circumferential flange 13 that repeses on the aforementioned seat or shoulder 9 when the parts are assembled, while the main or inner part thereof is downwardly dished as clearly shown in Figure 2 so that it is disposed in spaced relation relative to the concave-convex extension 6 of the reservoir 5. rl`his sealing pan 12 is also provided below the flanged part 13 thereof with a plurality of laterally opposed holes or elongated apertures 1e for a purpose later on explained.

Seating` a friction fit in the main body portion or reservoir 5 and adapted to hold the aforesaid sealing pan 12 firmly in place a` superposed dished diaphragm 15 having a lateral circun'ifcrential flange 1G, and fash ioned in vertical cross section to a dished contour as shown by Figure 2, so that when the parts are assembled it will be in spaced relation relative to the upper face of the sealing pan 12. lt is also to be particularly noted that this dished diaphragm 15 is of a depth relative to that of the sealing pan 12, so that its inner lewermost level is in direct horizontal alignment or in a plane with the lower edges of the aforesaid holes or elongated apertures 14 in said sealing` pan 12, while it is axially apertured at 17 to provide communication thereinto.

A cover or cap 18 is suitably screw threaded on to the top of the main body portion or reservoir 5 and it is internally fitted with a leather or other suitable material washer it) that serves as a packing to create an air lock as between said cap 0r cover 1S and the reservoir 5. This cap or cover 18 is also appropriately knurled or serrated at 2t) whereby a firm hold can be taken thereof to remove or replace said cap or cover 18 as desired, or when filling and 'refilling` the reservoir 5.

A n air vent 21 is provided below the sealing pan 12 but above the lower level of the holes elongated apertures 11i therein. and it serves for the automatic replacement of the air which bubbles up through the axial hole 1T as the lubricant 22 flows downwardly after each splash7 and thereby recreates the seal at the lever 2B.

The assembly and functioninoof my novel lubricator or Oil cup as above escribed will be clearly apparent to those conversant with the art to which this invention appertains, while it will be obvious that l have provided an oil cup or' lubricator comprising a minimum. number of parts, in factexcluding the washer 19-only four in number and all of which can be manufactured by die stamping` or casting from sheet metal.

Furthermore, I wish to particularly emphasize the formation of the dished diaphragm 15 and an examination of Figure 2 more particularly will clearly establish the fact that the formation shown ensures the full weight or pressure of the lubricant being axially directed over the outlet 1T. This feature is deemed of considerable importance as it effectively ensures the automatic action of the lubricator or oil cup until the main body portion or reservoir is completely emptied.

llVhile there has been shown and described one practical embodiment of my invention, l wish it clearly understood that I do n ot limit myself t0 the precise details' specilically set forth, as it will be perfectly obvious the same are susceptible of modification to adapt my said invention to different sizes and types of lubricators; the right is therefore hereby reserved to maire all such changes and modifications as fairly lie within the scope of the appended claim.

Having described my invention, what l. claim as new and desire to secure by Letters Patent is:

A lubricator comprising a reservor of cylindrical form, a screw threaded nipple integral therewith, said nipple being of smaller diameter than the cylindrical portion at the punction therewith to provide a shoulder, the lowerniost extremity of said nipple having` a restricted opening for the passage of the lubricant, a sealing' pan of conc-avo-c'onvex cross section supported by the aforementioned shoulder, said sealing; pan being of lesser diameter than the cylindrical portion 0l" the reservoir, a (lished dia.- phragm frictionally 'engaged with the walls of the cylindrical portion of the reservoir, said diaphragm being' supportefjl by the aforementioned shoulder, said sealing pan being held in position by said diaphraim. apertures in the walls of said sealing` pan intermediate the centre and periphery thereof, and an air-tight 'seal for the reservoir.

ln testimony whereof I afiix my signature,

GELE STIN S'ANNER.
